AUDIBLE SIGNAL FOR MOTOR-VEHICLES.

'Applieation filed December 26, 1919. Serial No. 347,282.

To all whom it may concern:

Be it known that I, CI-innvnn C. CoNLnn, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Audible Signals for MotorVehi.cles, of which the following is a specification. 7

This invention relatesto motor vehicles, and the primary object of the invention is toprovide an improved means for sounding a warning signal when an unauthorized person or persons starts the engine, thereby reducing the likelihood of a vehicle being stolen to a minimum.

Another object of the invention is to provide an attachment for internal combustion engines of motor vehicles embodying a siren, whistle or the like, adapted to be operated by the exhaust gases of the engine, and so constructed as to be brought intoalinement with the exhaust pipe, and lockedin such a position so that upon the operation of the engine .by unauthorized persons, the siren, whistle or the like, will be operated, thereby calling the owners attention to the fact that the vehicle is being tampered with.

Another object of the invention is to provide an exhaust operatedsignal for motor vehicles, which may be locked into operative position by the driver of the vehicle when leaving the machine to provide a theft signal, or which may be operated upon the option of the driver from his seat and used as an ordinary roadwarning signal. a

A still further object of the invention is to provide an improved device of the above character which is durable and efficient in use, one that is simple and easy to manufacture, and one which can be placed upon the market and installed upon a machine at a reasonable cost.

Other objects of the invention will appear 'in the following detailed deserlptlon, taken in connection with the drawings, forming a part of this specification, in which drawingsa Figure 1 1s a fragmentary side elevation of a motor vehicle showing the improved,

device applied thereto tion.

Fig. 2 is a vertical longitudinal section through the device.

Fig. 3 is. a detail fragmentary section taken on the line 33 of Fig. 5.

Fig. 4. is a vertical horizontal section and in locked positaken through the device at right angles to Fig. 2, she-wing the device in signaling position.

Fig. 5 is a front elevation of the device showing the exhaust pipe in section.

Fig. 6 is a view similar to Fig. 4; showing the device in non-signaling position, and for permitting the free flow of exhaust gases through the same, and

Fig. 7 is a detail perspective view of the means for operating the device from the drivers seat.

Referring to the drawings, in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A indicates the improved device, which is adapted to be associated with the exhaust pipe B of the in ternal combustion engine C of a motor vehicle D. The means for operating the attachment is designated by the numeral E.

The improved attachment A includes a casing 10, which may be attached in any desired position on the exhaust pipe, such as at the intersection of the exhaust pipe with the exhaust manifold tube, or at the intersection of exhaust tube with the muffier, or at the discharge end of the muffler, or in any position upon the exhaust pipe between the engine and mulfler. As shown, the casing is connected to the exhaust pipe adjacent to the engine so that the same can be conveniently reached by the operator upon the liftin up of the hood of the motor vehicle.-

. The casing 10 includes a front and rear plate 11 and 12 having aligned openings 13 formed therein for the passage of the products of combustion therethrough. The front and rear plates 11 and 12 are held in their correct positions by side plates 14:, which are arranged intermediate the upper and lower terminals of the side plates and secured thereto by bolts or rivets 15, which also extend through the attaching flanges 16 formed on the'sections' 17 and 18 of the exhaust pipe B. The flanges 16 formed on the sections'of the exhaust pipe surrounds the openings 13 formed in the front and rear plates 11 and 12, and if so desired, packing gaskets may be interposed between the flanges and front and rear plates for preventing the escape of the exhaust gases from the casing.

The casing 10 has slidably mounted therein a solid slide block 19 which has its sides providedwith reduced guide ways 20 which define upper and lower shoulders 21 and 22, which are adapted'to engage the outer surfaces of the side plates 14, and these shoulders form means for limiting the movement of the slide block in the casing. 7

The slide-block 19 hasformed therein a pair of spaced openings 23, and 24, which are adapted to be brought into alinement with the openings 13 formed in the casing at theoption of the driver of the motor vehicle. IVhile the openings are spaced from each other, the same are arranged in relatively close relation, so as to not obstruct the passage of the exhaust gases during the sliding of the block in the casing. The upper opening 23 forms means for permitting the free unobstructed'flow of exhaust gases through the casing, and the same is normally held in alinement with the openings in the casing by the weight of the slide block, and the downward movement of the block is limited by the upper shoulders 21.

The lower opening 24: is .adapted to receive a siren, whistleor any other preferred type of signal 25, and when the bloclris in its raised position, the signal is brought intov alinement with the openings in the casing, and thus be operated by the exhaust gases. When the block is in its raised position, the lower shoulders22 engage the lower face of the side plates 14 and thus prevent the openings 24 from being-moved out-ofregistration with the openingsin the casing.

The lowen terminals ,of the-front and rear walls 11 and 12 areprovided with alined apertured ears 26, which are adapted to aline with the apertured ear '27'formed on the lower end of the slide-block, when 7 the slide block is in its raised position, and

whenthe apertured ears. 26 and 27 are in alinement, the same are adapted to receive the shackle 28- of anordinary or any preferred type of padlock 29.

In operation of the improved attachment,

the driver of the vehicle raises the block 19 in the casing 10 when he leaves the motor vehicle and locks the block in its raised position by means of the padlock 29 as heretofore stated, and if a person starts the engine the products 'of combustion will sound the siren, whistle or the like, and thereby'call attention to the fact that the vehicle is being tampered with.

To permit the device to be used as an" ordinary signal an operating means E is provlded, which lncludes a foot operated lever30 arranged adjacent to the drivers" seat, and the lever is connected to a suitablelink 31, which is provided with'an outer forked terminal 32 having slotted arms'33 whichslidably and pivotally receive pins 3 1 formed onthe sides ofthe block 19 adjacent to the upper end thereof. I Thus it can be seen by pushingdown on the foot lever 30 that the block will be raised and the siren or whistle brought into alinement with the exhaust pipe. Upon the removal of pressurefrom the foot lever the block 19 will drop to. its normal position by gravity.

Whether or not the muffler is cut out makesvery little difference in operation of the signal. lVith the muffler cut out the warning would be somewhat louder, but in either case the noise would be sufficient to call attention to the fact that the alarm was chine being stolen.

Changes in detailsmay be made without departing from the spirit or scope of my inventionybut, 7 l
